Indentification research of natural deformation in excavating ancient ruins and tomb process is important for tracing or enriching the history and the prehistoric deformation historic record. Recently,the earthquake department of Anhui Province cooperated with the cultural relic archaeology department to conduct special macro and micro researches at Anhui Shouxian Dingjiagudui ruins archaeology scene. The natural deformation traces show that the cultural layers are cut by the sand veins. The preliminary study demonstrates that this is a seismic liquefaction vestige,which took place from the Longshan Time to the Western Zhou Dynasty. The project will help promote the identification of earthquakes in the cultural layers in Eastern China.
